Specification of Letters Patent.

Patented Feb. 6, 1906.

Application filed March 16, 1905. Serial No. 250,353.

To all whom it may concern:

Be it known that I, GEORGE H. TERRY, a perspective view of citizen ofthe United States, residing at Leslie, in the county of Ingham, State ofMichigan, have invented certain new and useful Improvements inCement-Fence-Post Molds; l and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to thefigures of reference marked thereon, which form a part of thisspecification.

This invention relates to cement-fencepost molds; and it consists in theconstruction and arrangement of parts hereinafter fully set forth, andpointed out particularly in the claims.

The objects of the invention are to provide simple and efficient meansfor molding fenceposts of cement, the arrangement being such as toenable the mold to be quickly placed in position, the fence-post shapedtherein, and the mold at once removed without disturbing the post, saidmold being adapted to be again set up to mold a succeeding post, and soon, the same mold being adaptable for moldingas many posts as desired.

A further object is to provide a mold of the character described oflight, strong, and durable structure so formed as to insure rigidity inthe sides thereof, obviating all springing or warping of the sides andenabling the mold ing of any number of posts desired of unvarying form.

A further object is to rovide for varying the length and also thediameter of the posts and also to provide for clamping the sides uponthe end gates in a manner to allow said sides to be readily removedafter the post is formed.

The above objects are attained by the construction illustrated in theaccompanying drawings, in which Figure 1 is a perspective view of myimproved mold in position for use. Fig. 2 is a plan view of Fig. 1. Fig.3 is an enlarged transverse section through the sides of the mold. Fig.4 is a fragmentary view in elevation, showing by dotted lines the mannerof removing the clamping-yokes. Fig. 5 is a one of the end gates.

Referring to the characters of reference, 1 designates the sides of themold, which are preferably formed of compara 'ively thin metal to renderthem sufiiciently light for handling and which are provided with thelongitudinally-extending strengtheningfianges 2 and 3 at the top andbottom, respec tively, and the interposed longitudinally-extendingstrengthening bead l. By means of the strengthening bead and flanges theside is rendered sufficiently rigid to prevent it from springinglaterally, thereby insuring a uniform shape to the posts. Interposed between the sides is the upper end gate 5 and the lower end gate 6.

It will be noted that the sides of the mold taper from the lower towardtheir upper ends and that the lower end gate 6 is correspondingly largerthan the upper end gate. By reason of the taper to the sides of the moldand the difference in the sizes of the upper and lower end gates thepost formed in the mold is rendered equally tapering on all sides. Theend gates are supported against the opposed beads or shoulders 7 and 8,formed upon the inner faces of the sides at their upper and lower ends,respectively. By, having a plurality of said beads or stop-shoulders thepost may be varied in length and also varied in transverse diameter.

To make a post of the largest possible diameter, the end gate 6 at thebase of the mold is placed against the stops 8 at the extreme ends ofthe sides and the upper end gate 5 is placed against the lower of theupper stops 7, as shown by dotted lines in Fig. 2.

In ordinary use the end gates will be placed as shown in Fi 1, the upperend gate against the stops at the extreme upper ends of the sides andthe lower end gate against the uppermost stops 8 at the lower endsthereof.

To provide for clamping the sides together so as to hold them inposition when the cement is being placed therein, there are employed aplurality of U-shape yokes or clamps 9 of various sizes adapted toengage over the sides of the mold at a point where the mold issufliciently narrow to allow the parallel side arms 10 of the clamps topass thereover, when bysliding the clamps toward the larger end of themold they may be made to tighten thereon and securelyhold the sidesagainst expansion.

It will be noted on referring to Fig. 3 that the lower ends of the sidearms 10 of the clamps engage the bead 4 on the sides of the mold, whilethe central portions of said arms engage the upper flanges 3. By thisarrangement the sides are held at their bottom edges as well as at theirtop edges and are prevented from springing outwardly at the bottom whenthe plastic cement mixture is being tamped therein. Each of the clampsis provided upon the depending arms thereof with the transverse bars 11,which bear upon the upper flanges 3 of the sides and hold the clamps inan upright position, the ends of said bars also affording afulcrum-bearing to enable the clamps to be pried off of the sides afterthe post has been formed by forcing the upper part of the clampsidewise, as shown by dotted lines in Fig. 4.

On referring to Fig. 3 itwill be noted that the bottom edges of thesides are slightly rounded, as at 12, whereby they are caused to tipoutwardly when the clamps are removed therefrom, enabling them to beeasily removed.

In using this mold it is only necessary to find a smooth surface, suchas a barn-floor or other convenient place where the molded posts may beleft to season. The mold is then set up upon this floor or surface withthe end gates between the sides so positioned as to form the size ofpost required. The plastic cement mixture is then placed in the mold andtamped to cause it to perfectly fill the same, when the clamps areremoved, enabling the sides and ends to be taken away and again set upfor a succeeding operation,

the formed posts remaining undisturbed until such time as they shallhave become sufliciently seasoned to allow handling.

Having thus fully set forth my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. A cement-fence-post mold, comprising the opposed flaring sides, eachof said sides having marginal strengthening-flanges, and alongitudinally-extending strengtheningbead interposed between saidflanges and the clamping-yokes adapted to embrace the sides and to bearupon said strengthening-flanges and said bead.

2. A mold for cement fence-posts, comprising the opposed tapering sidesarranged to diverge and having strengthening-flanges, the end gatesmovably located between said divergent sides, a plurality ofclamping-yokes of various sizes adapted to embrace said sides betweentheir ends, and to slide into binding relation therewith.

3. A mold for cement fence-posts comprising the converging metallicsides, having strengthening-flanges at their margins, and alongitudinally-extending strengthening-bead interposed between saidflanges, movable end gates located between said sides, clampingyokesadapted to embrace the sides and to bear against the flanges and beads,there being upon said yokes a supporting cross-bar adlapted to rest uponthe upper flanges of the sic es.

In testimony whereof I sign this specification in the presence of twowitnesses.
